Researcher Jie Feng, B.Eng and M.AppSc, began a one-year study as of January 3, 2005 to model the reflective fabric egg crates and geometrically analyze the relation between solar position and daylighting quality with Lighttex and comparatively sized blind/louvers.
The results of this study regarding two daylighting quality factors, illuminance uniformity and blocking of direct sun, indicate significant potential for Lighttex as a daylighting tool.
Lighttex panels and blind/louvers with various cell/strip sizes were modeled with lighting analysis software AGI32 during hourly time periods from 7:00 am to 7:00 pm on March 21, June 21, September 21 and December 21. Variances in uniformity were calculated under both clear and overcast sky conditions.
BLOCKING OF DIRECT SUN
Lighttex Sun Blocking Calculator calculates the amount of direct sun blocking with Lighttex and blind/louvers during the same time periods.
